It's 3x+2 because 3 ÷2 is 6 so it's 3x+2
F + V = E + 2
F = 25
V = 17
25 + 17 = E + 2
42 = E + 2
42 - 2 = E
40 = E <== there are 40 edges
Answer: 98268

Given: In an international company,
Employees in one country = 22,700
If this is 23.1% of the total number of company's employees,

Answer: x = 6.56
Step-by-step explanation: -0.4x - 0.5 + x = 3.63
-0.4x^2 - 0.5 = 3.63
-0.4x^2 = 4.13
0.63x = 4.13
x = 6.56
